KIEV, Aug. 11 (Xinhua) -- Ukrainian President Petro Poroshenko ordered Thursday to put all military units near the border with Crimea and in Donbass on high combat readiness.
He gave the order when meeting with the leadership of defense agencies and the foreign ministry.
Tensions between Russia and Ukraine have been escalating as Russia on Wednesday accused Ukraine of plotting terrorist attacks in Crimea and vowed to take additional measures to ensure the safety of infrastructure and citizens there.
Russia has prevented a series of terrorist attacks in Crimea planned by the Ukraine military intelligence service, the Russian Federal Security Bureau (FSB) said Wednesday.
The Ukrainian Defense Ministry immediately rejected the allegation, calling it Russia's attempt to justify its redeployment and actions in the region.
The autonomous republic of Crimea was absorbed into Russia in 2014 following a referendum, which was recognized by Moscow but rejected by Kiev.
